How can conditional statements be used to check and update variable values based on form submissions in PHP?

To check and update variable values based on form submissions in PHP, we can use conditional statements to determine if a form has been submitted and then update the variable values accordingly. We can achieve this by checking if the form has been submitted using the isset() function and then updating the variable values based on the form input. 

<?php
// Check if the form has been submitted
if(isset($_POST['submit'])){
    // Update variable values based on form input
    $name = $_POST['name'];
    $email = $_POST['email'];
    
    // Process the form data or perform any other necessary actions
}
?>

<form method="post" action="">
    <input type="text" name="name" placeholder="Name">
    <input type="email" name="email" placeholder="Email">
    <button type="submit" name="submit">Submit</button>
</form>
